怎么把二进制文件转成byte[] ?

[allenzz]

谢谢

FileInputStream fis = new FileInputStream();
byte[] data = new byte[fis.available()];
fis.read(data);
fis.close();

FileInputStream inFile = new FileInputStream(fileName);
ByteArrayOutputStream outByteArray =
new ByteArrayOutputStream();
int i = -1;
while ((i = inFile.read())!=-1)
outByteArray.write((byte)i);
byte[] byteArray = outByteArray.toByteArray();
inFile.close();
outByteArray.close();
return byteArray;
